The "Rise" singer appeared to do just that on Tuesday, as she celebrated her 32nd birthday jamming out to Kanye West at his concert at the Forum in Inglewood, California -- and filmed her hilarious reaction to his "Famous" line dissing Taylor Swift.

Interestingly enough, Perry and Swift -- and their mutual ex, John Mayer -- attended the same birthday party earlier this week. The singers both hit up Drake's 30th birthday soiree at Delilah restaurant in West Hollywood, California.
